What is WhatsApp Business API?

The WhatsApp Business API is an enterprise-grade communication interface developed by Meta (Facebook). Unlike the free WhatsApp app or the small-business-focused WhatsApp Business App, the API is built for medium to large businesses.

It's not an app you download—it's an integration that connects WhatsApp with your CRM systems, customer support platforms, chatbots & AI Agents, and messaging tools. This allows businesses to send and receive unlimited WhatsApp messages at scale. Learn more about WhatsApp marketing solutions and professional WhatsApp services.
